Again, Corrup Error preventing debugging real seaside exception

GLASS mailing list
Hi

I am clicking a button on my Seaside app and I get the attached screenshot. It looks like there is an original problem

'Error creating WAWalkback: a OutOfRange occurred (error 2110), for a VariableContext should be between 4 and 5'

Which is then lost when trying to log the exception.

Below is the gem log.  

Right now I would try to change #internalServerErrorMessage: to see if I can prevent the logError so that at least I am able to get the original exception so that I can debug it and know what it is about....

Re: Again, Corrup Error preventing debugging real seaside exception

GLASS mailing list

Which version of GemStone?

This looks to be some sort of error in trying to create a continuation in WAGemStoneWalkbackErrorHandler>>open: or WARemoteDebuggingWalkbackErrorHandler>>open:

And looks to be similar to the error that Paul has hit in 3.3.1

So...What I did is that in #open: I added code to write the ORIGINAL exception into the gem log:

   Transcript
                show:
                  (String
                    streamContents: [ :aStream | FACompatibilityUtils current printExceptionStack: err toLevel: 250 on: aStream ]).



With that, I got the following information (please note the parts in bold).

That's the info I could get for the moment.  Will continue trying to find more.

This looks like a smoking gun ... thanks ... I'll let you know if we need more information.

Hi

I am clicking a button on my Seaside app and I get the attached screenshot. It looks like there is an original problem

'Error creating WAWalkback: a OutOfRange occurred (error 2110), for a VariableContext should be between 4 and 5'

Which is then lost when trying to log the exception.

Below is the gem log.  

Right now I would try to change #internalServerErrorMessage: to see if I can prevent the logError so that at least I am able to get the original exception so that I can debug it and know what it is about....

Re: Again, Corrup Error preventing debugging real seaside exception

GLASS mailing list
OK... I tried to write down the exception into the object log (so that I can debug it with tODE) but I failed with all my attempts. 
So I guess we have just that plain text stack for the moment.

Ok, keep me informed if you find something!

Bye

Re: Again, Corrup Error preventing debugging real seaside exception

GLASS mailing list
In reply to this post by GLASS mailing list

Mariano,

This is a GemStone bug (internal bug #46661  "error 2110 from ExecBlock >>selfValue").

We'd like to be able to disassemble the home method of the ExecBlock that is causing the error, so that we can characterize (and fix) the bug properly. To that we need to get the oop of the ExecBlock from frame 9 of the stack ... given the oop of the ExecBlock, we'll be able to disassemble the home method and perhaps understand the root cause ...

Probably the best way to get the oop of the ExecBlock is to install a modified version of the proposed patch for the bug and log the oop of the receiver:

login as SystemUser and patch ExecBlock>>selfValue with the following:

method: ExecBlock
selfValue
"return self in an active copy , or nil if self is not referenced."
| theVc ofs |
theVc := staticLink .
theVc ~~ nil ifTrue:[ | vcOfs |
  vcOfs := self selfOffsetInVC .
  vcOfs > 2"VAR_CONTEXT_NAMED_SIZE" ifTrue:[
    vcOfs > theVc basicSize ifTrue:[

        GsFile gciLogServer: 'Bug46661 ExecBlock oop: ', self asOop printString.

       ^ nil "workaround bug 46661"].
    ^ theVc _primitiveAt: vcOfs
  ].
].
ofs := self _selfOffsetInSelf .
ofs ~~ 0 ifTrue:[
  ofs := ofs - 1 .
  ^ self _primitiveAt: ofs .
].
^ nil
%

When you get the oop of the ExecBlock, use the Oop in the following and remove the gciLogServer: from the patch.

Here's sample topaz code that you can run, once you get the oop of the exec block (our sample is based on getting the oop of the default sort block for a SortCollection.

Which version of GemStone?


3.3.3
 

This looks to be some sort of error in trying to create a continuation in WAGemStoneWalkbackErrorHandler>>open: or WARemoteDebuggingWalkbackErrorHandler>>open:

And looks to be similar to the error that Paul has hit in 3.3.1


So...What I did is that in #open: I added code to write the ORIGINAL exception into the gem log:

   Transcript
                show:
                  (String
                    streamContents: [ :aStream | FACompatibilityUtils current printExceptionStack: err toLevel: 250 on: aStream ]).



With that, I got the following information (please note the parts in bold).

Mariano,

This is a GemStone bug (internal bug #46661  "error 2110 from ExecBlock >>selfValue").

We'd like to be able to disassemble the home method of the ExecBlock that is causing the error, so that we can characterize (and fix) the bug properly. To that we need to get the oop of the ExecBlock from frame 9 of the stack ... given the oop of the ExecBlock, we'll be able to disassemble the home method and perhaps understand the root cause ...

Probably the best way to get the oop of the ExecBlock is to install a modified version of the proposed patch for the bug and log the oop of the receiver:

login as SystemUser and patch ExecBlock>>selfValue with the following:

method: ExecBlock
selfValue
"return self in an active copy , or nil if self is not referenced."
| theVc ofs |
theVc := staticLink .
theVc ~~ nil ifTrue:[ | vcOfs |
  vcOfs := self selfOffsetInVC .
  vcOfs > 2"VAR_CONTEXT_NAMED_SIZE" ifTrue:[
    vcOfs > theVc basicSize ifTrue:[

        GsFile gciLogServer: 'Bug46661 ExecBlock oop: ', self asOop printString.

       ^ nil "workaround bug 46661"].
    ^ theVc _primitiveAt: vcOfs
  ].
].
ofs := self _selfOffsetInSelf .
ofs ~~ 0 ifTrue:[
  ofs := ofs - 1 .
  ^ self _primitiveAt: ofs .
].
^ nil
%

When you get the oop of the ExecBlock, use the Oop in the following and remove the gciLogServer: from the patch.

Here's sample topaz code that you can run, once you get the oop of the exec block (our sample is based on getting the oop of the default sort block for a SortCollection.

So...maybe it is a none persistent object? 

BTW should the workaround have fixed the original issue? Because I am still getting the Corrupt error even with the patched selfValue.

Thanks!

Which version of GemStone?


3.3.3
 

This looks to be some sort of error in trying to create a continuation in WAGemStoneWalkbackErrorHandler>>open: or WARemoteDebuggingWalkbackErrorHandler>>open:

And looks to be similar to the error that Paul has hit in 3.3.1


So...What I did is that in #open: I added code to write the ORIGINAL exception into the gem log:

                show:
                  (String
                    streamContents: [ :aStream | FACompatibilityUtils current printExceptionStack: err toLevel: 250 on: aStream ]).



With that, I got the following information (please note the parts in bold).

That's the info I could get for the moment.  Will continue trying to find more.

Hi

I am clicking a button on my Seaside app and I get the attached screenshot. It looks like there is an original problem

'Error creating WAWalkback: a OutOfRange occurred (error 2110), for a VariableContext should be between 4 and 5'

Which is then lost when trying to log the exception.

Below is the gem log.  

Right now I would try to change #internalServerErrorMessage: to see if I can prevent the logError so that at least I am able to get the original exception so that I can debug it and know what it is about....

Re: Again, Corrup Error preventing debugging real seaside exception

GLASS mailing list
Darn, the ExecBlock isn't persistent then ... well, the next best thing is to get the #sourceString of the home method for the block and/or the #blockSource of the block. So we'll add a bit more logging information to ExecBlock>>selfValue:

          GsFile gciLogServer: 'Bug46661 ExecBlock oop: ', self asOop printString.
          GsFile gciLogServer: 'Bug46661 ExecBlock blockSource: ', self blockSource.
          GsFile gciLogServer: 'Bug46661 ExecBlock homeMethod inClass: ', self method homeMethod inClass printString.
          GsFile gciLogServer: 'Bug46661 ExecBlock homeMethod selector: ', self method homeMethod selector asString.
          GsFile gciLogServer: 'Bug46661 ExecBlock homeMethod source: ', self method homeMethod sourceString.

With regards to additional corrupObj errors, we are hitting the patch, so there must be more than one failure mode involved. Can you get us the stack from the other corruptobj errors? The stack should be slightly different.

Mariano,

This is a GemStone bug (internal bug #46661  "error 2110 from ExecBlock >>selfValue").

We'd like to be able to disassemble the home method of the ExecBlock that is causing the error, so that we can characterize (and fix) the bug properly. To that we need to get the oop of the ExecBlock from frame 9 of the stack ... given the oop of the ExecBlock, we'll be able to disassemble the home method and perhaps understand the root cause ...

Probably the best way to get the oop of the ExecBlock is to install a modified version of the proposed patch for the bug and log the oop of the receiver:

login as SystemUser and patch ExecBlock>>selfValue with the following:

method: ExecBlock
selfValue
"return self in an active copy , or nil if self is not referenced."
| theVc ofs |
theVc := staticLink .
theVc ~~ nil ifTrue:[ | vcOfs |
  vcOfs := self selfOffsetInVC .
  vcOfs > 2"VAR_CONTEXT_NAMED_SIZE" ifTrue:[
    vcOfs > theVc basicSize ifTrue:[

        GsFile gciLogServer: 'Bug46661 ExecBlock oop: ', self asOop printString.

       ^ nil "workaround bug 46661"].
    ^ theVc _primitiveAt: vcOfs
  ].
].
ofs := self _selfOffsetInSelf .
ofs ~~ 0 ifTrue:[
  ofs := ofs - 1 .
  ^ self _primitiveAt: ofs .
].
^ nil
%

When you get the oop of the ExecBlock, use the Oop in the following and remove the gciLogServer: from the patch.

Here's sample topaz code that you can run, once you get the oop of the exec block (our sample is based on getting the oop of the default sort block for a SortCollection.

So...maybe it is a none persistent object? 

BTW should the workaround have fixed the original issue? Because I am still getting the Corrupt error even with the patched selfValue.

Thanks!

Which version of GemStone?


3.3.3
 

This looks to be some sort of error in trying to create a continuation in WAGemStoneWalkbackErrorHandler>>open: or WARemoteDebuggingWalkbackErrorHandler>>open:

And looks to be similar to the error that Paul has hit in 3.3.1


So...What I did is that in #open: I added code to write the ORIGINAL exception into the gem log:

That's the info I could get for the moment.  Will continue trying to find more.

Hi

I am clicking a button on my Seaside app and I get the attached screenshot. It looks like there is an original problem

'Error creating WAWalkback: a OutOfRange occurred (error 2110), for a VariableContext should be between 4 and 5'

Which is then lost when trying to log the exception.

Below is the gem log.  

Right now I would try to change #internalServerErrorMessage: to see if I can prevent the logError so that at least I am able to get the original exception so that I can debug it and know what it is about....

Darn, the ExecBlock isn't persistent then ... well, the next best thing is to get the #sourceString of the home method for the block and/or the #blockSource of the block. So we'll add a bit more logging information to ExecBlock>>selfValue:

With regards to additional corrupObj errors, we are hitting the patch, so there must be more than one failure mode involved. Can you get us the stack from the other corruptobj errors? The stack should be slightly different.


OK. First, I attach what I get rendered by Seaside. Then in `blockInfo.txt` you have the printing of the ExecBlock. Finally, I attach the stack. Note that the error now happened on another place. So I had to add the write down of the stack here (see bold part)


seasideProcessRequest: aNativeRequest adaptor: adaptor resultBlock: resultBlock
  | result |
  [ 
  self retryDelays
    do: [ :retryDelay | 
      (result := self
        seasideProcessRequestWithRetry: aNativeRequest
        resultBlock: resultBlock) ~~ nil
        ifTrue: [ ^ result ].
      System _sessionCacheStatAt: 2 put: (System _sessionCacheStatAt: 2) + 1. "requests retried"
      (Delay forMilliseconds: retryDelay) wait ]. "exceeded retry limit"
  ^ adaptor
    internalServerErrorMessage:
      'Too many retries: ' , (self retryDelays size + 1) printString ]
    on: Error

      result := adaptor internalServerErrorMessage: ex description. "Do an explicit return. Because of the abort above, the default action for an exception (resume) is set. see bug39246."
      ex return: nil ].
  ^ result

OK, let me know if you need something else.

Mariano,

This is a GemStone bug (internal bug #46661  "error 2110 from ExecBlock >>selfValue").

We'd like to be able to disassemble the home method of the ExecBlock that is causing the error, so that we can characterize (and fix) the bug properly. To that we need to get the oop of the ExecBlock from frame 9 of the stack ... given the oop of the ExecBlock, we'll be able to disassemble the home method and perhaps understand the root cause ...

Probably the best way to get the oop of the ExecBlock is to install a modified version of the proposed patch for the bug and log the oop of the receiver:

login as SystemUser and patch ExecBlock>>selfValue with the following:

method: ExecBlock
selfValue
"return self in an active copy , or nil if self is not referenced."
| theVc ofs |
theVc := staticLink .
theVc ~~ nil ifTrue:[ | vcOfs |
  vcOfs := self selfOffsetInVC .
  vcOfs > 2"VAR_CONTEXT_NAMED_SIZE" ifTrue:[
    vcOfs > theVc basicSize ifTrue:[

        GsFile gciLogServer: 'Bug46661 ExecBlock oop: ', self asOop printString.

       ^ nil "workaround bug 46661"].
    ^ theVc _primitiveAt: vcOfs
  ].
].
ofs := self _selfOffsetInSelf .
ofs ~~ 0 ifTrue:[
  ofs := ofs - 1 .
  ^ self _primitiveAt: ofs .
].
^ nil
%

When you get the oop of the ExecBlock, use the Oop in the following and remove the gciLogServer: from the patch.

Here's sample topaz code that you can run, once you get the oop of the exec block (our sample is based on getting the oop of the default sort block for a SortCollection.

So...maybe it is a none persistent object? 

BTW should the workaround have fixed the original issue? Because I am still getting the Corrupt error even with the patched selfValue.

Thanks!

Which version of GemStone?

This looks to be some sort of error in trying to create a continuation in WAGemStoneWalkbackErrorHandler>>open: or WARemoteDebuggingWalkbackErrorHandler>>open:

And looks to be similar to the error that Paul has hit in 3.3.1


So...What I did is that in #open: I added code to write the ORIGINAL exception into the gem log:

That's the info I could get for the moment.  Will continue trying to find more.

Hi

I am clicking a button on my Seaside app and I get the attached screenshot. It looks like there is an original problem

'Error creating WAWalkback: a OutOfRange occurred (error 2110), for a VariableContext should be between 4 and 5'

Which is then lost when trying to log the exception.

Below is the gem log.  

Right now I would try to change #internalServerErrorMessage: to see if I can prevent the logError so that at least I am able to get the original exception so that I can debug it and know what it is about....

Re: Again, Corrup Error preventing debugging real seaside exception

GLASS mailing list

Mariano,

This second error is not related to the earlier error we were tracking ... I don't see an actual error message in your email, so I'm not exactly sure what is breaking here ... Nonetheless, #changeClassTo: was a nasty little performance hack that is no longer needed.

In GRUtf8CodecStream>>nextPutAll: the following should be done:

  binary
    ifTrue: [ stream nextPutAll: aString asString ]
    ifFalse: [ stream nextPutAll: aString _encodeAsUTF8intoString ]

and in Utf8>>asString the following should be done:

    ^ self decodeToUnicode

It is odd that this "trick" is failing now (especially without an error message), but I think the right answer is to eliminate the use of #changeClassTo:

With regards to additional corrupObj errors, we are hitting the patch, so there must be more than one failure mode involved. Can you get us the stack from the other corruptobj errors? The stack should be slightly different.


OK. First, I attach what I get rendered by Seaside. Then in `blockInfo.txt` you have the printing of the ExecBlock. Finally, I attach the stack. Note that the error now happened on another place. So I had to add the write down of the stack here (see bold part)


seasideProcessRequest: aNativeRequest adaptor: adaptor resultBlock: resultBlock
  | result |
  [ 
  self retryDelays
    do: [ :retryDelay | 
      (result := self
        seasideProcessRequestWithRetry: aNativeRequest
        resultBlock: resultBlock) ~~ nil
        ifTrue: [ ^ result ].
      System _sessionCacheStatAt: 2 put: (System _sessionCacheStatAt: 2) + 1. "requests retried"
      (Delay forMilliseconds: retryDelay) wait ]. "exceeded retry limit"
  ^ adaptor
    internalServerErrorMessage:
      'Too many retries: ' , (self retryDelays size + 1) printString ]
    on: Error
    do: [ :ex | 
      self doAbortTransaction.

      result := adaptor internalServerErrorMessage: ex description. "Do an explicit return. Because of the abort above, the default action for an exception (resume) is set. see bug39246."
      ex return: nil ].
  ^ result

OK, let me know if you need something else.

Cheers

Mariano,

This is a GemStone bug (internal bug #46661  "error 2110 from ExecBlock >>selfValue").

We'd like to be able to disassemble the home method of the ExecBlock that is causing the error, so that we can characterize (and fix) the bug properly. To that we need to get the oop of the ExecBlock from frame 9 of the stack ... given the oop of the ExecBlock, we'll be able to disassemble the home method and perhaps understand the root cause ...

Probably the best way to get the oop of the ExecBlock is to install a modified version of the proposed patch for the bug and log the oop of the receiver:

login as SystemUser and patch ExecBlock>>selfValue with the following:

method: ExecBlock
selfValue
"return self in an active copy , or nil if self is not referenced."
| theVc ofs |
theVc := staticLink .
theVc ~~ nil ifTrue:[ | vcOfs |
  vcOfs := self selfOffsetInVC .
  vcOfs > 2"VAR_CONTEXT_NAMED_SIZE" ifTrue:[
    vcOfs > theVc basicSize ifTrue:[

        GsFile gciLogServer: 'Bug46661 ExecBlock oop: ', self asOop printString.

       ^ nil "workaround bug 46661"].
    ^ theVc _primitiveAt: vcOfs
  ].
].
ofs := self _selfOffsetInSelf .
ofs ~~ 0 ifTrue:[
  ofs := ofs - 1 .
  ^ self _primitiveAt: ofs .
].
^ nil
%

When you get the oop of the ExecBlock, use the Oop in the following and remove the gciLogServer: from the patch.

Here's sample topaz code that you can run, once you get the oop of the exec block (our sample is based on getting the oop of the default sort block for a SortCollection.

So...maybe it is a none persistent object? 

BTW should the workaround have fixed the original issue? Because I am still getting the Corrupt error even with the patched selfValue.

Thanks!

This looks to be some sort of error in trying to create a continuation in WAGemStoneWalkbackErrorHandler>>open: or WARemoteDebuggingWalkbackErrorHandler>>open:

And looks to be similar to the error that Paul has hit in 3.3.1


So...What I did is that in #open: I added code to write the ORIGINAL exception into the gem log:

That's the info I could get for the moment.  Will continue trying to find more.

Hi

I am clicking a button on my Seaside app and I get the attached screenshot. It looks like there is an original problem

'Error creating WAWalkback: a OutOfRange occurred (error 2110), for a VariableContext should be between 4 and 5'

Which is then lost when trying to log the exception.

Below is the gem log.  

Right now I would try to change #internalServerErrorMessage: to see if I can prevent the logError so that at least I am able to get the original exception so that I can debug it and know what it is about....

The error message is the one of the screenshot rendered in the browser (attachment named "Screen Shot 2017-02-01 at 5.13.31 PM.png").
 

Nonetheless, #changeClassTo: was a nasty little performance hack that is no longer needed.

In GRUtf8CodecStream>>nextPutAll: the following should be done:

  binary
    ifTrue: [ stream nextPutAll: aString asString ]
    ifFalse: [ stream nextPutAll: aString _encodeAsUTF8intoString ]

and in Utf8>>asString the following should be done:

    ^ self decodeToUnicode

It is odd that this "trick" is failing now (especially without an error message), but I think the right answer is to eliminate the use of #changeClassTo:


Thanks!! Those changes DID fix it!!!  Wow...it was hard one this one... I am glad we find it. Do you need anything more from me to open issue or whatever? I will live with overrides for the moment. 

BTW, are you sure about performance? Because I remember that changeClass: hack did improve performance significantly. I wouldn't want to loos that performance boost!

Thanks a lot

Darn, the ExecBlock isn't persistent then ... well, the next best thing is to get the #sourceString of the home method for the block and/or the #blockSource of the block. So we'll add a bit more logging information to ExecBlock>>selfValue:

With regards to additional corrupObj errors, we are hitting the patch, so there must be more than one failure mode involved. Can you get us the stack from the other corruptobj errors? The stack should be slightly different.


OK. First, I attach what I get rendered by Seaside. Then in `blockInfo.txt` you have the printing of the ExecBlock. Finally, I attach the stack. Note that the error now happened on another place. So I had to add the write down of the stack here (see bold part)


seasideProcessRequest: aNativeRequest adaptor: adaptor resultBlock: resultBlock
  | result |
  [ 
  self retryDelays
    do: [ :retryDelay | 
      (result := self

        ifTrue: [ ^ result ].
      System _sessionCacheStatAt: 2 put: (System _sessionCacheStatAt: 2) + 1. "requests retried"
      (Delay forMilliseconds: retryDelay) wait ]. "exceeded retry limit"
  ^ adaptor
    internalServerErrorMessage:
      'Too many retries: ' , (self retryDelays size + 1) printString ]

      ex return: nil ].

OK, let me know if you need something else.

Mariano,

This is a GemStone bug (internal bug #46661  "error 2110 from ExecBlock >>selfValue").

We'd like to be able to disassemble the home method of the ExecBlock that is causing the error, so that we can characterize (and fix) the bug properly. To that we need to get the oop of the ExecBlock from frame 9 of the stack ... given the oop of the ExecBlock, we'll be able to disassemble the home method and perhaps understand the root cause ...

Probably the best way to get the oop of the ExecBlock is to install a modified version of the proposed patch for the bug and log the oop of the receiver:

login as SystemUser and patch ExecBlock>>selfValue with the following:

method: ExecBlock
selfValue
"return self in an active copy , or nil if self is not referenced."
| theVc ofs |
theVc := staticLink .
theVc ~~ nil ifTrue:[ | vcOfs |
  vcOfs := self selfOffsetInVC .
  vcOfs > 2"VAR_CONTEXT_NAMED_SIZE" ifTrue:[
    vcOfs > theVc basicSize ifTrue:[

        GsFile gciLogServer: 'Bug46661 ExecBlock oop: ', self asOop printString.

       ^ nil "workaround bug 46661"].
    ^ theVc _primitiveAt: vcOfs
  ].
].
ofs := self _selfOffsetInSelf .
ofs ~~ 0 ifTrue:[
  ofs := ofs - 1 .
  ^ self _primitiveAt: ofs .
].
^ nil
%

When you get the oop of the ExecBlock, use the Oop in the following and remove the gciLogServer: from the patch.

Here's sample topaz code that you can run, once you get the oop of the exec block (our sample is based on getting the oop of the default sort block for a SortCollection.

So...maybe it is a none persistent object? 

BTW should the workaround have fixed the original issue? Because I am still getting the Corrupt error even with the patched selfValue.

Thanks!

This looks to be some sort of error in trying to create a continuation in WAGemStoneWalkbackErrorHandler>>open: or WARemoteDebuggingWalkbackErrorHandler>>open:

And looks to be similar to the error that Paul has hit in 3.3.1


So...What I did is that in #open: I added code to write the ORIGINAL exception into the gem log:

That's the info I could get for the moment.  Will continue trying to find more.

Hi

I am clicking a button on my Seaside app and I get the attached screenshot. It looks like there is an original problem

'Error creating WAWalkback: a OutOfRange occurred (error 2110), for a VariableContext should be between 4 and 5'

Which is then lost when trying to log the exception.

Below is the gem log.  

Right now I would try to change #internalServerErrorMessage: to see if I can prevent the logError so that at least I am able to get the original exception so that I can debug it and know what it is about....

The error message is the one of the screenshot rendered in the browser (attachment named "Screen Shot 2017-02-01 at 5.13.31 PM.png").
That error message was "CorruptObj" and the error message I was looking for was the error message from the #changeClassTo: ... The stack that you supplied us with was different from the #changeClassTo: stack, as I didn't see selfValue on the stack ... doesn't matter though
 

Nonetheless, #changeClassTo: was a nasty little performance hack that is no longer needed.

In GRUtf8CodecStream>>nextPutAll: the following should be done:

    ifFalse: [ stream nextPutAll: aString _encodeAsUTF8intoString ]

It is odd that this "trick" is failing now (especially without an error message), but I think the right answer is to eliminate the use of #changeClassTo:

Please open an issue against Grease ... up on SeasideST so that we can get the fix in ... the #changeTo: hack looks like it went in around 3.2.2, so I'm not exactly sure when _encodeAsUTF8intoString was added to the system (it was added to replace the #changeTo: hack)...

BTW, are you sure about performance? Because I remember that changeClass: hack did improve performance significantly. I wouldn't want to loos that performance boost!
Well, the issue that changeClassTo: was trying to solve was the conversion of the Utf8 instance (ByteArray) into a String (required by Seaside). #'_encodeAsUTF8intoString' encodes utf8 directly into a String instance .... so the performance should be no worse than #changeClassTo:

Uhhh I forgot to ask.... is the change on #selfValue still needed? I mean....sure I can remove it and test, but I am wonder on other scenarios than mine. Please let me know.

Yes, there is a bug in selfValue --- the source of the corruptObj error ---we haven't  characterized the bug, until we understand the cause, a corruptObj error could occur anytime an attempt to create a continuation is made or a even debugger opened , so yes you should leave the #selfValue patch in until we get to the bottom of the VCContext bug...

Dale,

Note that the #nextPutAll: is indeed for Grease and I opened an issue there. But the change on Utf8 >> asString is part of GemStone itself. Would you open an issue for that one too so we don't forget? if true, then please share with me the issue number (I keep track of these).

Thanks

Mariano,

Utf8>>asString is part of GsDevKit (GLASS1) ... it's in the Core322x package ...
